Rocker arms in wrong places

[Paul G]

Putting my new Stealth heads on I noticed that one of the push rods for #1 cylinder had been rubbing against the old head. Upon further investigation I found that the knucklehead who put my engine together many years ago had the rocker arms in the wrong places, just on #1 cylinder.

I put them in the right places now on the new heads but I am questioning weather I should get new rockers since these have a wear pattern on them, or if I can just use them as they are?

How much wear?  Personally, when it comes to things like that if I'm unsure I prefer to err on the side of caution and replacement.

Might as well change them....seems like not only a different wear pattern, but possibly could have caused some fatigue on the rocker and the push rod. Better to be safe

If the other rockers are in good shape just replace the pair on #1

I called the local machine shop and talked them. The shop foreman sais to bring in the rockers and the pushgrods for him to see. He said he can order just the two of them and two pushrods for me.

I asked if there was a way to tell if they are 1.5's or 1.6's. He said that if they are stamped steel stock type rockers they are 1.5's.

My next question: How much could I expect to pay for just the two rockers and pushrods?

Is there any benefit to upgrading all the rockers to 1.6's? What all will need to be replaced to make the swap to 1.6"s? Cost?

Here's what they look like.
In the first pic you can see the pushrod rubbing on the head.
Second pic is how the rockers are way off center on the valve stem.
Third pic is the underside of the rockers, and you can see the worn spot on the push rod. I can really feel the indent in the pushrod.

I never noticed this last year when I did the cam swap

Paul, you can clearly see the rocker arms are reversed in those pics....replace the rocker arms and the pushrods as well if you can feel or see some wear on them.
